So, when I play as rohan, their banner carrier upgrade doesnt seem to work. I can purchase the upgrade at the armory, but when I go to an individual unit, the upgrade banner carriers button is still greyed out, so I cant press it. I looked around on the forums for help, but I couldnt find this problem. Is this an acknowledged bug in the game, or is there something wrong with my copy. I have reinstalled the game several times with the same result. Thanks for your help in advance
